FYI, replacement drivers are $46USD each, so at this point in time I believe that I will take the two step approach:

1) Replace the 3 drivers in the VP1502) Use the feature on the HK 7200 which limits the volume.

Only question is, how do I know what to set the upper limit at? Is there some physical way to know just by listening? Or would I need an oscope?

BTW, I did not have the receiver set to "Loud", it was on "Soft"

Having the volume limit set on the receiver is always a good idea no matter what. This will prevent your speakers from any damage in the future from your wife or guests, but the reason why your wife turned up the volume so loud was to get sound across the house and even OUTSIDE mind you. That is the big problem you have to solve. This is an unreasonable and ridiculous application to begin with and now adding a volume limiter to get reasonable volumes of music through multiple rooms and outside from a distant room won't work very well IMO.

There are not only spouses to worry about, but if you own any pets. I paused a movie I was watching and went to use the the restroom one time. My cat at the same time jumped up on and couch and laid down on top of the remote and the volume slowly went up to max. I ran out there (I think that I zipped up) and quickly lowered the volume, so it was only for a couple of seconds, but that is an easy way to damage some drivers. At that point I set the volume limiter to -13dB, which is way too loud for me.

Vicky's Secrets?Is that like Victoria's Secrets but for rednecks and all the model's wear extra large stretch pants or seriously undersized gym pants and pose with rifles while spread across the McDonalds counter at Walmart?

Oh Sorry, that is the Vicky Joe's Secrets catalog. Shake and Bake Brotha!!!!
